• ### How to Calculate the Refractive Index in Physics 7 Steps

· Refractive index of the second medium (in which the refractive ray travels) with respect to the first medium (in which the incident ray travels) is the ratio of sine of the angle of incidence to the sine of the angle of refraction. So in this case the refractive index is sin 30 / sin 60 which calculates to 1/root 3=1/1.732 equal to 0.6.
